Who knew that grass on a hike could be a really, really bad thing? Well, Sequoia National Park isn't just home to your average lawn grass. This is grass-grass, and the stashes are guarded by armed drug cartel men at all times. Yup, drug dealers are using fertile American national park land to plant their farms, and they've been doing it for years. The weed was planted less than a half mile from the park's popular Crystal Cave tourist area. For six days in 2009, officials had to shut down the park in order to fly in rangers by helicopter to dismantle the operation. Another exploit at the Indiana Dunes National lakeshore contained about 10,000 plants valued at $8.5 million. Now that's what I'd call a cash crop.
